4.5.6.1 Water supply line
The connections should be hand tightened using PTFE (plumber’s tape) on the threads if using the
threaded connection type.
In case of heat welding (metal type connection), the connections should not be made to the valve
when soldering.
Info
See chapter Description and component location [ → Page 22] to identify the
connections.
When pressurized, any composite tank will expand both vertically and circumferential. In order to
compensate the vertical expansion, the piping connections to the valve must be flexible enough to
avoid overstress on the valve and tank.
